10 Claims. (Cl- 282-8) This invention relates in general to multiple manifolding devices and more particularly to the multiple carbon sheets having a common leader attached thereto for use on billing machines and typewriters and adapted to economize ,and facilitate the application and use of carbon paper in multiple manifolding.

An important object of the invention is in the provision of a plurality of carbon sheets attached to a common leader and adapted to be separately folded for use and for holding those not in use out of the way.

, A further object of the invention is in the provision of a leader sheet which has indicated folded lines thereon and overlaps a reserved magazine of carbon sheets to prevent the carbon sheets not being used from engaging the sheets being manifolded.

A still further object of the invention is in the provision of a flexible sheet leader with a plurality of carbon sheets attached thereto by a seam cut off at the ends to offer the least obstruction at these points as the multiple carbon holder is inserted between and moved relatively to the sheets which are manifolded.

Other objects of the'invention will appear in the specification and will be apparent from the accompanying drawing illustrating the invention, in which Fig. 1 is a perspective view of a leader sheet and a plurality of carbon sheets before they are attached together;

Fig. 2 is a perspective view of the sheets shown in Fig. 1 after they have been fastened together at one end;

Fig. 3 is a perspective of all carbon sheets with their free ends folded together under their other portions;

Fig. 4 is a perspective view illustrating the outermost carbon unfolded or extended for use, and the free end of the leader sheet folded to engage a bar of a manifolding machine and partially 0 folding devices particularly equipped to carry and type continuous forms. Such forms are now commonly used in manifolding machines either.

in the fanfold form with successive lateral openings on opposite sides or in the open web type in which a plurality of printed strips are foldable by means of which carbons 'are withdrawn to- 10 gether before the typed and manlfolded forms at the ends are torn off. As the lower edges of the carbons. become worn, they are removed several inches at a time until finally the carrier sheet comes close to the platen of the machine. In the 15 ordinary manifolding' installation, a new carbon sheet must be inserted and sometimes an entirely new sheet and attached leader must be replaced, depending upon the connection of the carbon sheet. In the present invention, it is necessary 20 only to unfold another carbon sheet from the multiple holder to extend it outwardly for use between the sheets which are manifolded, without inserting a new leader sheet.

Referring now more particularly to the drawing, a plurality of carbon sheets 10 are provided for each extension leader sheet H. The carbon sheets may have a carbon ink surface on one side only, or on both sides and interleaved by thin sheets of plain paper, the plain paper to act as a protecting sheet for the first carbon in the form preventing the type from cutting the carbon; also, these interleaved sheets may be used against the'ink surface of the carbon sheet to act as a block out to prevent certain information from registering on parts of any one copy of the form. The leader sheet is preferably of relatively tough, non-adhesive-material such as waxed paper or the like, slightly longer thanthe carbon sheets Ill and having a number of printed, perforated, ruled lines, or other score lines I 2 extending transversely thereof to relate or accommodate any size of carbon carrier. The ends of the carbon sheets of the leader sheet are placed togetherwith the reproducing faces of the carbon sheets all facing the leader sheet, and the lowermost surface engaging it.

With the extremities of the sheets at one end all registering, they are securely fastened together by staples or a row of stitching I3 which forms a somewhat stiffened rib or ridge at this location.

The corners ll of the sheets are therefore cut off at an angle either before the sheets are assembled or after they are stitched or fastened to- .or open .the scored fold of the manifold sheet or to bind therein, making it difllcult to withdraw themultiple carbon holder before the manifold copies are torn off.

After the carbon sheets are attached to. the leader, they are all folded over inwardly about a line l5, approximately midway of their length, the carbon sheets either being folded separately or altogether and lying flatly against the surface of the leader sheet ll. The free end ii of the leader sheet is likewise folded over inwardly about a fold line I! which may coincide with one of the connected fold lines If and this forms a cover extending over the outsideof the carbon sheets when they are not in use.

In order to apply this multiple holder to a manifolding machine, the free end or flap of the leader sheet is raised and a manifold attachment bar I8 is inserted transversely therethrough, the leader sheet being looped, over the bar or wrapped around the bar to attach the leader thereto in a well known manner. At this time, the outermost carbon sheet is unfolded from the others and extended forwardly therefrom along the line of the seam as indicated more clearly in Fig. 4 and this carbon sheet is then extended between the sheets for manifolding to make a copy thereof. The free end ll of the leader sheet is then folded flat against the remaining carbon sheets where it is retained flatly in position by the superposed manifolding sheets between which the carbons are inserted.

After once being placed in position between sheets which are being manifolded, it is a simple matter tocontinue the use of all of the carbon sheets in succession until they are entirely used up, it being necessary only to raise the next carbon sheet and extend it after the preceding one has been used up. In this manner, it is not necessary to attach the leader or to insert a new one, or to'insert a new carbon sheet each time one sheet of 'carbon is used up. The free end It of the leader sheet being folded over, the folded end ii of the carbon sheets prevents them frombeing engaged, raised or torn by the manifold sheets as the carbons and carbon holders are moved relatively to the manifolding sheets in advancing them to the printing position.

If desired, carbon sheets may be stitched or folded at slight angles for insertion on the left or right sides of a fanfold form or when carbon sheet is unfolded and extended for use between the parts of the form, it may be inclined at the stitch line so that it (the carbon sheet) will be feeding at a slight angle, pointed toward the closed side of the form; this angle of feeding will prevent the carbons from pulling out from the open sides of the form as the operator pushes the carbon carrier backward to withdraw the carbons from the completed form, prior to tearing off the finished form.

The infolding of the carbon sheets and the overlapping of the extension leader, provides means for handling the carbon sheets without soiling the hands, with the least smearing of the carbon itself and with the least danger of smearsince only one'sheet of carbon is exposed at a time. The carbons and leader sheets may be of various sizes and lengths, but a single fold of both is considered best as the folding of a leader sheet and several sheets of carbon for each sheet to be manifolded, produces a considerable bullr, weight and thickness which tends to tear the manifold forms apart at their folded edges and .prevents the carbons and holders from sliding freely with respect to the manifold sheets. This is another reason for making the leader sheet of smooth or waxed paper which does not adhere readily or form an obstruction to the sheets at either side of it. a

' I claim:

1. In a multiple carbon, a plurality of carbon sheets, one on top of the other, 'a leader sheet therefor, and means for securing all the sheets together at one end thereof, the sheets being folded inwardly midway of their lengths and the leader covering the ends of the carbon sheets.
